Hi all -- At long last my Terak 8510/a is working again! I'd repaired the power supply a couple of years back but the system simply would not behave properly. I traced it down to some very unreliable IC sockets (they were not high-quality when they were new, and the damp environment this particular machine spent several years in before I got it did nothing to help). I finally replaced about 40 sockets with some nice turned-pin ones last week, and now the system is up and running and passing the System Acceptance Tests with flying colors. I do not have a keyboard or monitor for this system, and while it's pretty easy to fabricate replacements (the video's just standard composite, and the keyboard is an 8-bit parallel ASCII keyboard with a few extra special keys) I'd love to find a set of originals. If anyone has any spares in any condition, please drop me a line. (I'm also interested in tracking down an original single-density floppy controller just on the off chance...) Thanks! - Josh
